After hitting a small compression rise during Saturday’s downhill at Val d’Isere, France, she came down hard on her damaged right knee and pulled out of the race by skiing off the course.

Vonn told reporters she had “not hurt herself more than I’m already hurt” and felt she could still make it to February's Sochi Olympics by cutting back on racing until then.

In a tweet posted several hours after the race, Vonn said her entire ACL is damaged again.

``Bummed about today,'' Vonn wrote. ``Skiing with no ACL is hard! Will see how it responds over the next few days and then make a plan'' #notgivingup#Sochi2014

Saturday’s was her fourth World Cup race since undergoing reconstructive knee surgery after a crash last February and reinjuring the knee in an early November crash. Vonn's publicist had issued a statement a few days after that accident that described the new injury as a partial tear of the anterior cruciate ligament that had been surgically rebuilt last winter.

``I'm fighting as hard as I can to keep my Olympic dream alive but skiing with no ACL is harder than I expected,'' Vonn said later Saturday on her Facebook page.

Vonn said Saturday her weight was completely on the right ski after hitting the compression.

“My knee just completely gave out,” she said. “I tried to put pressure on the ski again, and it gave out again.”

Vonn, defending Olympic champion in the downhill, said she does not expect to race again until January.

“I just need to be more careful about the number of races I do,” she said. "I’m at risk of doing more damage to my knee. So I am going to play it safe and race (a) really minimal (number of) races. Probably just one or two before the Olympics."

Vonn, 29, had raced two downhills and a Super-G Dec 5-7 on her favorite course in Lake Louise, Canada, finishing 40th, 11th and 5th. She skipped last weekend’s races in St.Moritz, Switzerland.
